In a statement, Northvolt says its validated cell is more safe, cost-effective, and sustainable than conventional nickel, manganese and cobalt (NMC) or iron phosphate (LFP) chemistries and is produced with minerals such as iron and sodium that are abundant on global markets.

It is based on a hard carbon anode and a Prussian White-based cathode, and is free from lithium, nickel, cobalt and graphite. Leveraging a breakthrough in battery design and manufacturing, Northvolt plans to be the first to industrialize Prussian White-based batteries and bring them to commercial markets.

Reports across the web also say the technology enables the supply chain to become ecologically more sustainable, cheaper, abd less dependent on China.

I'll believe it when I see it.

This isn't some futuristic technology. Na-ion was originally researched at the same time as Li-ion but didn't show enough commercial promise in the 1990s.

Sodium-ion batteries have already been deployed in a few locations. The energy density is only 160 Wh/kg (compared to 100-220 for Li-ion) so you won't see it in personal devices, but for applications where space isn't at a premium, this technology is already in market.

I believe you mean mass, not space if you cite the energy density per kg.

[–] crispy_kilt@feddit.de 3 points 11 months ago (1 children)

Technically correct (best kind) but in reality, to get the same capacity, you'll need more mass, which uses more space as well.

[–] taladar@feddit.de 9 points 11 months ago

Well, it is a big difference when we are talking about applications like air or space travel where space might be a lot easier to increase than the capacity to carry extra mass.

I swear we hear about a new battery technology every week.

[–] shootwhatsmyname@lemm.ee 9 points 11 months ago

There’s this new company called Duracell that’s making these AA batteries which seem promising too

[–] RTRedreovic@feddit.ch 8 points 11 months ago

I heard about these sodium-ion batteries a few years ago. I don't really care much about these until they are actually in the market.

Battery capacity has almost tripled in the last decade.

[–] pelya@lemmy.world 7 points 11 months ago (2 children)

Probably in 10 years, because it's a car battery, and it takes time to pass all regulations. Notable absense of comparing it to Lithium battery, so definitely not targeted at smartphones. It will get installed into your nearest wind farm first.

[–] Ophioparma@feddit.de 2 points 11 months ago

For now the manufacturers themselves see their market mainly in african and middle-eastern countries. So maybe not even the nearest wind farm depending on where you live.

I spotted that also.

In terms of BESS, my experience is that the bigger issue has been designing cubicles that don't leak or catch fire.

This isn't some technology being researched, it's an actual product in development. I'd certainly take their numbers with a pinch of salt but the premise is solid.
